As long as I've been in this vortex of an addiction that we call head-fi, there are still a few things (more than a few actually) that I know little about. One of them being the benefits of power chords, power conditioners, power supply upgrades, etc..
My speaker rig that I have is run by my Arcam A75 integrated amp. I love it to death, but there is a slight hiss (well, more than a slight hiss) I can't seem to get rid of. I've tried using my Kefs instead of my Infinities. I've tried using different outlets around the house. I've tried using different surge protectors. I do however think that I can find my answer in upgrading the power supply to both my source and integrated amp. I have upgraded my headamps power supply (HR Cosmic) by buying the Cosmic power supply upgrade off of headroom and have had astonishing results. The space between the notes became extremely silent, the bass increases in both quantity and quality, and the treble energy also stepped up a notch in quality. The thing is, in trying to find something for my Arcam, I do not know what the equivilent is to receiving the same results as I do with my Cosmic power supply upgrade? I also would like to buy something similar for my Rega Planet 2000 source as I know this would help too...it surely couldn't hurt, right?
If anyone wishes to help me out, perhaps you can first start off by explaining to me what the differences (and definitions) are between upgrading power cords, upgrading the power supplys, and upgrading or adding power conditioners. And if there is anything I'm missing, be sure to iunclude that too. If I can spend 100$ on each upgrade (amp, source), then so be it. But spending more than that is something I'd like to avoid unless absolutely neccessary. Even better, if this hiss problem can be fixed without any of these upgrades, I would like to accomplish that first...but I will not entirely ignore the possible benefits that can be had by upgrading the power supplys (or whatever I upgrade).
I should note that the power cord coming out of my Arcam is permanently fixed (I guess is the correct term??) inside the component while the power cord on my Rega is detachable.
Any help that can be offered is greatly appreciated. Enjoying my speaker system through the Arcam A75 is getting to the point of becoming a huge annoyance because of the loud hiss getting in the way of the music (especially on classical recordings
).
One more thing. I also should mention that my Onkyo receiver has no problems with any hissing or humming...it is perfectly silent, with all speakers I've ever hooked up to it. Also, the headphone out on the Arcam shows the exact same results as it does with the speaker outputs...a damn annoying hissss!
